To all whom, t may concern:

Be it known that 1, DANIEL F. LEPLEY, a citizen of the United IStates, residing at Connellsville, in t-he county of Fayette and State of Pennsylvania, have invented a new and useful Coke-Discharging Apparatus, of`

which the following a specification.

This invent-ion has reference to improvements in coke 'discharging apparatus and is designed to provide ameansOr breaking up Lhe coke block as it-is discharged from acoke oven, into large pieces and at the same time free it from coke dust and ashes.

'lt is customary to provide, coke ovens in long series and along the series of ovens is a ledge or embankment for a trackdesigned to carry a truck upon which is mounted a suitable conveyer for receiving the coke as it is discharged from the ovens and for conveying it to cars which in turn are supported l upon a track at the outer edge of the bank or ledge.

In accordance with the present invention the coke, as it is discharged from an oven by means of a. pusher entering the oven from the remote end, is engaged by an accelerator tending to lift the Vblock of'coke and at the vsanV i. time increase the movement of the lower surface of the block, thus causing 30 of the hard skin which forms on the bottom of the coke block. lThe lifting of the broken ott portion also tends to causethe gravitation of coke dust and ash, which accumulate on the top ofthe block, from the same. The accelerator, is in the form of a slatted drum and adjacent thereto there is provided a grating upon which the broken ottA portions of the coke block tall so that thexlisintegrated scale and the ashes and coke dust.-

-nd escape through both the accelerator drum and the grating to a suitable point of deposit whilethe broken coke is carried by a conveyer to a suitable point and is there deposited in cars or other suitable containers.

rI`he invention 1s designed tor use particularly with coke ovens where the coke is dis-` of this specification, in which drawin04s dirt from the coke is deposited near the oven front. y

The invent-ion will be best .understood from a consideration of the following detail description taken in connection with the accompanying drawings forming a part :wa Figure l is a. side elevation of the structure for receiving the coke as discharged from the oven, as viewed from the power end of the sustaining truck which latter is shown in end elevation. Fig. 2 is a plan view of the structure shown in Fig. l. Fig.

3 is a longitudinal section of .a coke oven showing the oven end of the coke receiving apparatus and an indicative representation of a coke pusherJ at the respective endsV of the coke oven.

InJ Figl there is shown more or less diagrammat-ically one end of a coke oven l with the adjacent ledge o1' embankment 2 extending to near a car track upon which it is assumed that cars are run and the body 8 of one of these cars is simply indicated in this figure. Mounted upon the ledge 2 parallel with the face of the ovens l it being understood that the ovens are arranged in 1on1r series, are rails 4-4 the inner one of which may be located about midway between the mouth of the oven and the outer edge of the ledge 01 embankment 2.V Upon the rails 4 there is mounted a truck5 which may be of any suitable construction and consequently need not be described in detail herein. Near one. end of the truck there is mounted a prime mover preferably in the form of an electric motor G connected by means of suitablegearing which need not be described in detail, to a shaft 7, and also through other gearing to one -of the axles of the truck, clutches 8MS) being interposed at appropriate points so that the motor may be coupled to the shaft 7 or to the truck axle at will. The truck carries at such points as may be necessary cross beams 10 of suitable length and disposition to support certain structures to be hereinafter described.

Mountedin suitable bearings carried by appropriate ones ot the cross beams 10 is an arbor 11 parallel with the longitudinal axis of the truck and located between the truck and the coke ovens. The arbor 11 carries a miter gear-l2 in mesh with a miter pinion 13 on the shaft 7 so that when mo.-

The traine vcomposecl.

At the saine time the higher speed of movement of the periphery of'the drum 1S over and above the progressive movement of the colte core. together with the elevation of the enil ot the coke core Causes the latter to irraiitture on a substantially vertical plane because there a` ce ain vertical stratification ot `the core that is characteristic of colic.
